Should everyone get a second chance after messing up?
It depends on how badly this messing up involves others. A bus driver falling asleep at the wheel killing several of his passengers shouldn't, at least not a second chance at bus driving.
As a person yes, unless loss of human life from a deliberate act.
For many things, yes.
What about a second chance as a person? No second chance as a driver - even if it were an honest mistake and wouldn't be repeated?
In God's eyes or man's eyes? In God's eyes we do. In man's eyes, we usually don't.
Yes; after I give everyone else their first chance.
Should we give second chances more than we do?
